Comparing Strength of Electromagnets and Neodymium Magnets at 4 oz and 12v

AI Thread Summary
When comparing the strength of electromagnets and neodymium magnets at 4 oz and 12v, electromagnets generally scale better for larger applications, while neodymium magnets are preferable for smaller quantities. Electromagnets are not limited by voltage but by current, which can lead to overheating if not monitored, especially with a 2 Amp power supply. For applications exceeding 1 lb, using electromagnets with an iron core is recommended. Neodymium magnets are effective for lighter loads due to their strong magnetic properties. Overall, the choice between the two depends on the specific weight and application requirements.

Which one is stronger given they are the same size and weight? Say 4 oz.

Just say you only have 12v to work with on the electromagnet.

Electromagnets scale better then neodymium.
For small quantities, I would say go for neodymium.
Anything past 1lb or so, I would use electromagnets with a iron core.

Also, electromagnets aren't limited by the voltage, but rather the current (as its essentially a short circuit)
I've used 2Amp power supplies before, however you need to keep an eye out on the electromagnet as it will warm up and burn out quickly.
 
That's good news. Thanks for the info you saved me tons of time.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
